    @srishtyagrawal No, I wasn't aware of stateSave hence thought about 
implementing session. Please ignore about cookie.
    
    @revans2 Thanks for the info. I see how it will work.
    
    For me it would be ideal if we can extract paging size from state data and 
store/load it globally (in stateSaveCallback/stateLoadCallback), so table in 
topology B starts from length 50 if I changed the length from somewhere else. 
It will require understanding of state data in DataTables (and upgrading 
DataTables might break the functionality) and I'm not sure even it is possible, 
so please treat this as just a 2 cents.
